1. An expandable slide and lock stent, the stent comprising a tubular member having circumferential and longitudinal axes, the stent comprising:

  • a first backbone;

    a second backbone;

    a third backbone;

    each of the first, second, and third backbones extending along at least a portion of the circumferential and the longitudinal axes, and each comprising;

    an open bond slot in a first portion of the respective backbone;

    a closed pass-through slot in a second portion of the respective backbone; and

    a recessed nesting area in a third portion of the respective backbone;

    the first portion being radially thinner than the second portion and being radially thinner than the third portion; and

    the third portion being radially thinner than the second portion;

    a rail member extending along at least a portion of the circumferential axis, the rail member comprising proximal and distal ends, wherein;

    the proximal end of the rail member is coupled to the first backbone at the open bond slot of the first backbone;

    the distal end of the rail member extends from the first backbone in a circumferential direction through the closed pass-through slot of the second backbone; and

    the rail member being slidably interfaced with the recessed nesting area of the third backbone;

    wherein the rail member is configured to provide one-way movement of the second and third backbones away from the first backbone such that the tubular member can be expanded between a collapsed diameter and an expanded diameter.
